Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 13; Rayons mous dorsaux (Total): 10; Épines anales 7; Rayons mous anaux: 9; Vertèbres: 13. Dusky blue dorsally, silvery below; a bright yellow spot adjacent to last few rays of dorsal fin; head with lines and spots. Preopercular angle 91°-102°; strong scales fully cover the cheeks; midline of thorax scaled, not the pelvic ridges. Anterior nostril with extremely low rim, slightly expanded posteriorly. Spines stout, pungent, venomous.

Biologie     Glossaire (ex. epibenthic)

Inhabits turbid inshore reefs among mangroves; tolerates or even prefers low salinities. Fry settles in seagrass beds around river mouths and adults enter and leave rivers with the tide, but also found on the drop-offs of inshore fringing reefs down to 6 m. Schools throughout life; school size for adults around 10 or 15. Feeds on benthic algae. Unlike other siganids, this species is reported to be active at night. Sold fresh in markets (Ref. 9813, 48637).
